In-office bleaching with a two- and seven-day intervals between clinical sessions: A randomized clinical trial on tooth sensitivity

Novel treatment of in‐office tooth bleaching sensitivity: A randomized, placebo‐controlled clinical study

“…In contrast to reports mentioning that 15%‐78% of patients experienced sensitivity after bleaching other investigations found only 16.7% to 26.7% BS . Even much lower BS values were published by various authors after tooth bleaching with 35% hydrogen peroxide gel immediately and short time after the whitening procedure . Our present data after PLA application and 40% hydrogen peroxide bleaching for 15 minutes showed a maximum score 3 on a 10‐point VAS scale during the bleaching procedure.…”

Effectiveness of 6% hydrogen peroxide concentration for tooth bleaching—A double-blind, randomized clinical trial

“…15,30 In relation to the absolute risk of sensitivity, data are consistent with that reported in the literature for both groups (36.66-50%). 28,31 However, the data differ from some reports that compared different concentrations like Bortolatto et al 9 Martin et al 16 presented results that suggest that a higher concentration of the bleach compound generates greater risk of sensitivity. The intensity of reported sensitivity was mild, which coincides with previous work by our group.…”

“…In future studies, the best application time should be determined, as well as intervals between sessions to achieve better performance of the compound with minor adverse effects. 27,28 Subjective outcomes measured by the variation of SGU units are shown to be inconsistent with the objective results. The subjective determination of tooth colour is challenged by high variability.…”

Stain removal effect of novel papain- and bromelain-containing gels applied to enamel

“…2). Tooth bleaching or stain removal procedures using whitening agents and following the Bin-office^strategy usually needs more than one clinical session to reach maximum effectiveness and patient satisfaction [4,24]. In the present study, both the experimental and carbamide peroxide-based gels produced a significant stain removal effect after their first application, although an additional application was necessary to obtain maximum benefit from the treatment.…”

“…Whichever strategy is used, both the Bat-home^and Bin-office^procedure may produce a long-lasting bleaching effect [2]. Notwithstanding, the former strategy is usually associated with lower tooth sensitivity when compared to the latter, as a result of low-concentration bleaching materials, compared to high-concentration materials that are involved in the Bin-office^procedure [3][4][5][6][7]. Indeed, the greater the hydrogen peroxide concentration used, the greater the probability for hydrogen peroxide molecules to diffuse through enamel and dentin, leading to hypersensitivity and/or pulp inflammatory reactions [8][9][10].…”
